Last year, Rome pledged to crack down on bad behaviour involving the city’s fountains, imposing fines of up to €240 (£215) for people caught snacking or camping on the fountains’ pedestals, dipping their feet in the water or going for a swim.

Residents are particularly irked by tourists who try to recreate the scene from Federico Fellini’s film La Dolce Vita, in which the late Swedish actor Anita Ekberg wades into the fountain.
